Lab Practical 1 Flashcards
Location of simple squamous epithelium
lungs, inside of heart and blood vessels
function of simple squamous epithelium
diffusion and secretion
function of simple cuboidal epithelium
absorption and secretion
location of simple cuboidal epithelium
kidney tubules and livers
location of simple columnar epithelium
from stomach to intestines, uterine tube
function of simple columnar epithelium
absorption and secretion
location of pseudostratified columnar epithelium
respiratory passages
function of pseudostratified columnar epithelium
secretes mucus and traps dust particles, moving them way from the lung
location of stratified squamous epithelium
epidermis, oral cavity, esophagus and vagina
function of stratified squamous epithelium
resists abrasion, prevents microbial infections, water retention in the skin
what does keratin do for stratified squamous epithelial cells
makes the barrier waterproof
location of transitional epithelium
urinary bladder
function of transitional epithelium
stretching of urinary bladder/is elastic
location of skeletal muscle
skeletal muscles, attached to bony skeleton
function of skeletal muscle
voluntary contractions
whats the pattern with the nuclei in skeletal muscle
nuclei are usually found in a line off to the side of the cell, leaving room for contraction
location of cardiac muscle
the heart
function of cardiac muscle
rhythmic heart contractions, involuntary
whats a pattern usually seen microscopically in cardiac muscle
-branched cells
-intercalated discs (thick and spaced out)
-less obvious striations (thin and populated)
location of smooth muscle
digestive tract, blood vessels, uterus
function of smooth muscle
involuntary sustained contractions, propulsion of food, delivery of infants
whats the shape of smooth muscle cells
small and slender with no striations
what does a typical neuron/glial cell look like
neuron: large and star shaped cells with branching
glial: small cells present around neurons in nervous tissue
where do you find neurons/nervous tissue
brain and spinal chord, nerves
function of nervous tissue
neurons transmit electrical signals from sensory receptors to effectors
glial cells support and protect neurons
location of dense regular connective tissue
tendons and ligaments
function of dense regular connective tissue
binds bones together or connects muscle to bone
location of dense irregular connective tissue
dermis, sheaths around cartilage and bone
function of dense irregular connective tissue
structural strength and resists against stress tearing
location of reticular tissue
spleen, thymus, lymph nodes and liver
function of reticular tissue
internal skeleton for your soft organs
location of areolar tissue
deep to the dermis and surrounding many internal organs
function of areolar tissue
binds epithelia to lower layers, insulates organs from infection
location of adipose tissue
under the skin, breast tissue, outside of the heart and kidneys
function of adipose tissue
energy storage and physical protection
location of hyaline cartilage
ends of long bones, ribs, larynx and trachea
function of hyaline cartilage
forms most of fetal skeleton, reduces frictions at joints, keeps air passages open
location of fibrocartilage
intervertebral discs and pubic symphysis
function of fibrocartilage
resists compression, reduce wear and tear
location of elastic cartilage
external ear and epiglottis
function of elastic cartilage
provides flexible framework
location of compact bone
skeleton
function of compact bone
protection of soft organs, locomotion along with muscles, support
location of spongy bone
ends of long bones surrounded by compact bone, inside vertebrae , ribs, skull
function of spongy bone
storage of bone marrow, site of erythropoiesis, reduces weight of skeleton, mineral storage
location of blood
heart and blood vessels
function of blood
transports respiratory gasses, nutrients, hormones, water through the body, immunity
